I made a non-deductible $20,000 contribution to my 401K in 2021 and then transferred it immediately to my brand new Roth IRA at Fidelity (I have another Roth IRA from many years ago). This is the so-called “mega back door” IRA and I can contribute up to $58,000 per year. I entered the relevant 1099-R into Turbotax and it says my Roth IRA contribution is over the allowed limit of $6000 and I must pay a penalty. How can I get turbotax to recognize the higher $58000 limit and NOT use the $6000 limit ?
To verify, you did not enter anything under IRA contributions, correct? If you did then delete this entry.
You only enter your Form 1099-R for this conversion and answered the follow-up questions to indicate it converted to the Roth IRA:
As @DanaB27 suggests, you've mistakenly entered this as a Roth IRA contribution. You did not make a regular Roth IRA contribution, so go back and remove that entry you made under Deductions & Credits. Only ther the Form 1099-R and in the follow-up questions indicate that you rolled the money over to a Roth IRA.
