if you filled box 1 and 3 and efiled and it was accepted you double reported the US interest. Box 3 was the only box to reprt US interest, Look at page I of 1040 line 2b that should show only 852 + any other interest
if it shows 1704 + your other interest you double reported. If your return was accepted you'll need to file an amended return to get back the overpaid taxes.
