Line 25 a,b,c, on form 1040-SR info was duplicated and entered only once

I received only ONE 10999R for the RMDS for 2024 and yet the amount is now being listed on 25b (correct) but the same amount is also showing up on line 25c for no reason.  Why????  In all the years we have used Turbo Tax, we have never had a problem!!!!!
