For now, you will have to wait, unfortunately. You need to wait until your return is either rejected or approved.
If it's rejected, you can return to the program to add the new information while fixing the error.
If your return is approved, you would need to amend if adding the 1099-Q information changes your original refund amount or tax due. Please come back later to this link 2019 Amend to amend. If you need to amend, wait until your return is fully processed and you have received your refund or your payment has cleared.
