For the military TPS. what do i put for my "additional contributions"

[chuckmorse115]

Let us know if you made any additional contributions to qualified retirement accounts
This is not common, but tell us if you made any after-tax additional contributions to qualified retirement accounts, or any contributions to an ABLE account.
Don't enter any of the $102.00 in regular elective contributions that you made to employer-provided qualified retirement accounts.
Additional contributions

[DanaB27]

You would enter an amount as after-tax contributions if you made additional after-tax contributions to your TSP that are not listed on your W-2. If you did not make any additional contributions then leave it blank.
