I've followed these instructions multiple times attempting to amend my 2023 business tax return through TurboTax online and it leads me to a 504 screen error. I have read through other posts and many are unable to amend their 2023 tax returns after following these instructions. Can you give us a different solution or get Turbotax to fix the problem?
