Like many others posting, I also received a “Taxable inherited IRA calculation error.” rejection by both Fed and State. Alarming considering, I do not have an inherited IRA.
However, I do have a nondeductible IRA RMA. TT prepared form 8606 as it has done for previous years without a problem.
I contacted TT customer service twice, both representatives were affable nevertheless denied TT Culpability and seemed oblivious to this problem.
The first representative suggested it must be a problem with my computer and open a case which closed within minutes after my phone call.
The second representative said my desktop CD (TT deluxe windows) has five free federal E-files, to use another E-file and refile. However, I would need to pay another $20 State E-filing.
Neither mentioned a pending March 5 update.
Anyone E-filing with the March 5 update, please post results.
Please contact TurboTax support through the following article.
March 5, 2021
I updated yesterday evening and refiled this afternoon without making changes, returns were accepted within 15 minutes. (Desktop CD - Win 10)
Thank you to those posting and updating.
