What do I do when turbo tax says I am older than I am? My birthdate is correct in the "my info" pages but on another page about RMD they are acting like I am a year older

Or did you inherit the account?  What code is in 1099R box 7 ?  

Here are the RMD rules from IRS Pub 590B…….
Your required beginning date. The date you must begin receiving RMDs is determined by the date you reach age 72. See the following to determine your applicable required beginning date.
