My first time building a shed by myself and it's been a lot of work, since it is on a slope. I got the piers and columns in, had it squared, and put cut plywood in the corners.
I cut all the joists, and I guess exhaustion and rushing, I didn't double check the squareness and I put all the joist hangers on and anchors from the rim joist to the 6×6 posts.. with 16d galvanized nails that are not coming out. Some how it shifted even with the corner braces. Guess plywood was a bad choice for holding square.
It was originally one inch off, but I got it down to 3/4.. knocking it with a 4lb sledge hammer..
What are my options? If I start framing how much will this effect the walls?

Use a ratchet strap or a come-along to pull the corners together on the diagonal that measures longer than the other, then, before removing this, secure a sheet or two of plywood down to the floor joists.
You can use some big eye bolts through the rim joists to give your ratcheting device something to hook into at either end.
You shouldn’t need to worry about damaging anything. 3/4” out of square means you’re compressing the long diagonal only 3/8”, and nails allow for some wiggle and play in the framing before it is sheathed with ply or boards.
I don’t recommend beating on the thing you’re building. It’s hard on your body, and doesn’t hold things precisely square for you while you do the other work to sustain the squareness once achieved, like laying plywood on the floor.
