Amended returns must be printed, signed and mailed. Assuming you did that, you can check on your amended return at this IRS site:
https://www.irs.gov/Filing/Individuals/Amended-Returns-(Form-1040-X)/Wheres-My-Amended-Return-1
And as already stated, it can take at least 16 weeks (or longer) for the IRS to process an amended return. If you are receiving a refund from that amended return, the IRS will mail a check to the address you used on the return.
