1099R

I have a 1099r from Charles Schwab the show in box 1 my RMD  that's correct but in box 2 it is the same #  Back in December of 19 I had C S sent 3 checks to 3 different charities  land  because of the new rules (the way I understand them you can direct them to send checks to the charities and you will not pay income tax on that amount } It seems to me the 1099R should in box to a lesser taxable amount .   Or can I just take and put the taxable amount in box 2 on the form  ( witch is 450.00 less!
