Hi, I am also a FERS Postal retiree (12-31-19). I am not withholding state taxes from my pension, since my state (Missouri) isn’t taxing my federal pension. You are probably not yet finalized. You can probably add a state deduction to your pension after you are finalized, if you think you need to. It might not be necessary. Ask a retired friend that lives in your state if they were charged state taxes in 2020, when they filed. A lot of states do not tax federal pensions. I haven’t yet withdrawn from my TSP. When I do, I might owe some Missouri state tax on my tsp withdrawal. I do not know if Missouri will tax my social security payments. I won’t get my first SS until December.
