By the way, you must very specifically arrange the "return" with the plan trustee. It is not a regular contribution, and regular contributions can't be counted as returns. If you want to use your weekly or monthly contribution funds to pay the return, you will need to stop the contributions, collect the money in your paycheck (after tax), and send a separate payment to the plan trustee using their specific procedure for a COVID return. (It may require a special paper form or a special election online.)
