If you've already e-filed your return, you cannot make any changes to it. Wait to see if the return is accepted by the IRS. If the IRS rejects the return for some reason, you can make changes before resubmitting. However, if the IRS accepts the return, no changes can be made.
If you're expecting a refund and requested direct deposit, the IRS will mail a paper check for the refund to the address on the tax return.
