Form 8606 Lines 16 and 18

My 1099R combines my two 2025 transactions: 1) a traditional IRA withdrawal, and 2) a traditional IRA to ROTH conversion (not a backdoor conversion).  This ROTH conversion had taxes withheld, leaving a reduced amount arriving in ROTH account.  My 1099R Boxes 1 and 2 are equal, as expected since both transactions above are taxable. 

 

A Form 8606 was generated showing the full amount of my ROTH conversion BEFORE tax withholding on both Lines 16 and 18, with no other Lines completed.  I have no after-tax contributions.  Is it correct that Lines 16 and 18 should show the gross ROTH conversion amount BEFORE tax withholding, or, should these 2 Lines show the net ROTH conversion amount AFTER my tax withholding?  Did I answer a TT interview question incorrectly? Thank you!

Lines 16 and 18 of your form 8606 should show the net amount converted to a Roth IRA.

 

When entering your 1099-R, in the follow-up interview, there was a question Tell us if you moved the money through a rollover or conversion, then on the next page  I converted some or all of it to a Roth IRA, you should enter the amount converted to a Roth IRA.  You probably entered the gross amount.

Thanks MinhT1

For my clarification, is the NET amount converted to a ROTH IRA you mentioned 1) the net amount of ROTH conversion after taxes are withheld that end up in the ROTH account, or, is it 2) the net amount of my total Traditional IRA withdrawals that was withdrawn for ROTH IRA purposes?  Thank you.

It is the net amount which landed into your Roth IRA.
