Get your taxes done using TurboTax

Ok, kind of the same issue as many people on here.  Doing a conversion on a Traditional Non Deductible IRA to a Roth.  I did 6K deposit into my Traditional account earlier in 2021, then immediately converted that to the Roth.  I still had a remaining balance in the Traditional (all non deductible), I then converted that remaining balance to the Roth.  Turbo has my cost basis correct.  It is handling the tax portion correctly, but it keeps giving me a warning & telling me my Magi is too high & that it is a excess contribution.  I know there are no dollar limits on converting an IRA to a Roth.  Why is giving me the warning & telling me there will be a penalty?  Thanks
