Non-taxable FERS Annuity supplement included in taxable amount in box 2a on 1099R

I am a retired federal public safety officer who did not have any earned income during 2022.  OPM has included the non-taxable FERS Annuity Supplement in the taxable amount in box 2a of my 1099R.  How can I report the reduced taxable amount in turbotax to reflect the non-taxable FERS Annuity?
