I'm using download deluxe version. I had the same issue with multiple errors on 2210AI during final review. 2210, underpayment of estimated taxes, in generating in situation that are not applicable. In my situation, if there was no prior year tax liability, no current year tax liability, no withholding (I'm retired), no estimated tax payment, but I had payments from prior year refund applied to current year and I'm receiving a refund this year. TT does not appear to be treating prior yr taxes applied to current yr the same as an estimated tax payment. Regardless, under IRS rules, no penalty is due since current tax liability is less than $1,000, current yr taxes withheld (withholding/estimated/applied from prior yr) are more than 90% of current tax liability, current yr taxes withheld (withholding/estimated/applied from prior yr) is at least 100% of prior years tax liability. I deleted the form since it was not applicable. I contacted TT about this and they did not acknowledge the bug.
