I amended my 2017 tax return to add a 1099-div today, but it was accepted by IRS yesterday. what will happen now?

You will need to wait until your original return has been fully processed and you have received your refund or your payment has cleared before sending your amendment.  Amended returns do not “catch up” to your original return and replace them; they are processed as two separate returns.  

Amended returns have to be printed and filed by mail.  It can take the IRS up to 12 weeks or longer to process them.   If you are due a larger refund than on your original return, your amended return should only show the difference and you will receive a separate check for it.  If you owe money on your amended return, it will show only the new amount owed, you will have to mail a check with the return.
