For Proseries Basic, Line 7 on the IRA Contributions worksheet, says Excess Traditional IRA Contribution credit.  I have a client who made a $4,300 excess contribution in 2019.  My understanding is that there is a 6% excise tax on that amount.  When doing the federal review for 2020, I came to that worksheet and I have to put an amount on Line 7 of the worksheet.  Can the client use this 4,300 for a 2020 credit and it then be a deduction on their 2020 return?  Does that remove the excise tax?  If so, can someone point me to the regulation for this?  Thanks.
