An amount on line 18 of Form 5329 had to be either user-entered or carried in from your 2023 TurboTax file. Examine line 10 of the IRA Information Worksheet in forms mode. If the amount is shone there in green, it transferred in from line 11 of your 2023 IRA Information Worksheet. If it's in blue, it's user entered.
"a carry forward of Roth contribution credits for 2025"
I'm not sure what you mean by that. What line of what form or worksheet?
