@Tax4fp Couldn't agree more! As a former programmer, I always put away the previous version of software incase the new modifications went bonkers. I still do that with spreadsheets. They knew the IRS changes in 2020 were temporary because of the covid stuff.
I love that this community has figured out the errors before the TT can even acknowledge them. I think early March I will file with a IRS provided form 2210 filed out with my spreadsheet values. I send hard copies, so I should be able to merge the two sources.
