Yes. Recontribution (repayment) of a CARES Act TDA withdrawal is optional.

If you take a CARES Act TDA withdrawal, you may choose to pay all or part of the withdrawn amount back into your TRS TDA account within three years of the distribution, provided you still have an open TRS TDA account to receive the repayment. See W12) below for additional information.

Note: Repayment of a CARES Act withdrawal is not a TDA contribution and does not count toward the annual contribution limit set by the IRS for in-service members.
