you will get a 1099-R at the end of the year (actually by the end of January 2026) and that's the Turbotax form that you will enter the info including distribution and withholding. don't wait until the last minute to take out the RMD. it sometimes happens, such events have been reported in this forum, that the payout is not accomplished by year end. special tax procedures are allowed to avoid the onerous penalties for late RMDs, but you really never want to go that route.
