Entering a nondecutible IRA contribution is decreasing my refund

I entered all my info for my 2022 federal return and have a refund of about $4,200.  yay

 

Then I remember that in 2014 I put $6,500 in an IRA thinking it would give me a tax break at that time.  Wrong, what was I thinking?  I was participating in an 401K in 2014.  The $6,500 was taxable, Turbotax walked me through including a 8606 with my 2014 return.

 

I retired in 2021 and took my first traditional IRA distribution in 2022.  I had already entered the 1099R for that distribution.  So I go back to the 1099R Entires and follow the wizard and I indeed get prompted with the question "Any Nondeductible Contributions to your IRA?"  This time I answer YES.  The cost basis auto-populates the $6,500 from the 8606 from 2014, Turbotax remembered that.  Then I am asked to enter my IRA balance as of December 30, 2022.  Done - My $4,200 refund is now $3,330!  Was it not suppose to decease my taxes?

 

If I go back to"Any Nondeductible Contributions to your IRA?" and say NO, my refund goes down to $3,200.  If I do it again, and answer Yes, it goes back to $3,330.  What happened to my $4,200 refund?

 

So I created a new return and entered all my income.  And sure enough, as soon as I say yes to"Any Nondeductible Contributions to your IRA?" about $1000 of my refund disappears.  Any idea what might be going on here?   Thanks.

 

Does anybody have an idea why this would be happening?
