How to enter ROTH conversion income in 2026

I didn't see any form to address my planned IRA to ROTH conversion for 2026 income. I don't need or want some TT program to go through some long process to tell me how much I need to send the IRS (Fed & NYS).  I just wanted TT to set up quarterly vouchers to pay the government and so avoid penalities.  I guess I will just do it on my own.
