The 2020 software failed to carry over a long term capital loss. I did not discover this until preparing the 2021 return. This required filing a paper amended 2020 return and a delay in filing 202I.I still don’t know whether the IRS has received the 2020 amendment as there are tremendous delays in the IRS even opening mailed in documents. I fear being subjected to audit and penalties. Next year I am using a tax accountant.
I have been using H&R Block software since 2011 and it has always been a successful and relatively stress free experience. No real complaints and the price is very reasonable.
