I thought I Played a Great Game then Discovered I had a 16.7% Accuracy?

Ya this happens a lot. You probably thought that all your pieces were working in harmony, attacking the king, everything was perfect. It is important to see what moves opponent can play to have counterplay (which didn't happen here fortunately)
Nice game!

And to build off of bluemu’s point, the reason it is almost always a mistake to trade bishop and knight for a rook and a pawn is because, as he said, you will rarely have the support pieces necessary to capitalize. This builds off, to some degree, opening tempo.
In chess tempo is the time necessary to generate an attack. In the opening, it usually means get all your pieces out ASAP. You typically don’t want to trade off developed pieces as that means your turn moving them was wasted (to a degree). Moving a piece a lot and then losing it means you lost those turns (in that you could’ve developed other pieces). As Nimzowitsch wrote “when a farmer loses a pig, he doesn’t only lose what it could fetch at the market, but what he fed the pig during its life.”
As applied to the Italian game trade-off, you would have moved the knight three times (Nf6, Ng4, Nxf2) and bishop twice (Bc5 and Bxf2) if white played better. Thus, you spend five turns and a knight and bishop (that are also well placed) to grab a rook and pawn that have 1 move between them and are terribly inactive (not attacking anything). Meanwhile, because white did castle, they have at least three tempi with a developed kingside knight and bishop and cornered (protected) king.
Not to say there aren’t moments where such a trade is warranted, but to say that on paper, it usually looks better to me not to trade.

Played a game today where I thought I was playing on the next level. I felt like I was channeling Magnus I even passed up an obvious fork on the rook and queen, because I wanted to keep up the pressure and get the checkmate, which I get.
I analyzed the game after and the computer assigned an accuracy of 16.7% to me? Can't you get that accuracy rating if you just randomly move pieces on the board?
What the heck?
I thought you played quite well, I don't understand Kh8 though

Thank You. I wanted to push my pawn forward on f7, but it was pinned by his bishop.

81.5% accuracy in this game. I'd be really p'd if this one
was low:
Wow, you played the traxler so well! Good going
It could be worse. You could get a 90% accuracy rating and lose. The percentage doesn’t matter. The ratings don’t matter either.
That is some of the best advice anyone can get!
wait wut. I was going to post a note asking whether ur name meant I am bacon or International Master Bacon. Apparently you blocked me. Why have I been blocked, just curious? Thanks
Stay on topic please. To answer that stale constantly asked question. Look at my profile page.
I will stop making forums unless I have a good reason from now on. and nice tips in ur profile btw, I never really thought about castling opposite sides and the effect it can have on a game
