No, you will not have to wait for them to process your son's amended return. But you can expect your mailed return to take a significantly longer time to be processed than an e-filed return--which is one of the sad effects of your situation. When you print the return for filing by mail, it will print out with the forms and schedules that you are supposed to include. You attach any W-2's and any 1099's that show tax withheld. You will not include mortgage 1098's, charity receipts etc. Save those for your own records.
Make sure you use a mailing service like certified mail so you will know the IRS receives it. It may take more than a month for a human to open your envelope and enter anything into the system, so you will have a wait to even see anything posted on the IRS refund site.
