I too have just found out based on an IRS audit of my 2021 tax return that turbo tax has been applying a carry over credit in error. Now I need to figure out what to do other than pay the $11,500 tax due and interest. I requested they forgive the penalty as I relied on turbo tax in good faith. Do I need to amend other year returns? Any help is appreciated. So upset that this was a known turbo tax error and they did not reveal it. I am done with turbo tax.
