Issue with 1099R and taxes withheld not calculating properly

I've seen other posts on this, however the responses haven't applied to my situation. I receive a public employee's pension as a former police officer. I am under the age of 59.5. My 1099R properly shows I had federal taxes withheld. But TurboTax is calculating the gross distribution amount as the full amount I received (aka: take home pay), whereas it should be showing a net amount received after taxes were withheld - but it is not factoring in the taxes that were withheld. How do I resolve this?
