Wow! You are right! Very observant! My own tax return shows the same problem.
Perhaps @BillM223 can help in reporting this bug.
I'll do a bit of research to see how long the bug has been present in TurboTax, but I suspect it's been there for a LONG time since it's not something that one would readily notice. Of course somebody who did not actually make an excess Roth IRA contribution would not care.
