Carry Forward of Deductions for Trust (deceased)

For 2022, our Trust (for Father deceased Oct 2021) will have $4K of interest income, and $10K of attorney fees (paid on 31 Aug), therefore $6K of unused deduction for 2022.

We expect his $5K final month rebate of his Federal Pension from OPM (U.S. Office of Personnel Management) to be finally paid in 2023 (with a 2023 1099-R), after more than a 14 month delay due to OPM federal backlogs.

•  The 14+ delay (federal backlog) forces the $5K income into 2023.  Otherwise, had it been processed in 2022 (full year to do so), the $10K attorney fee would have fully offset it.

 

Can we carry forward the 2022 $6K remainder attorney fee deduction to 2023 to cover the 2023 1099-R income? 

Are there other options? 

Or, are we forced to pay trust taxes in 2023 on the $5K income, solely because of the excessive OPM federal backlogs?
