How do I change the address of a 1099-INT payer?

You do not have to enter the address from 1099-INT forms.   Why do you need to change it? 

You don't need to enter the address for a 1099-Int. However, if your address is incorrect on the 1099-Int contact the issuer to have it corrected.

Mine is saying an address is required or else I cannot file electronically. It has the state, city, and zip code but the street address does not exist for that office.

@solanapearson  Let me guess.  Is it from the IRS?

Delete that 1099 and manually enter one with just the name IRS and put the interest amount in box 1.  You don't need to enter all that info on the form.

Or you can just enter anything in the street box.  It's not important.
