What is confusing you? You key in the information exactly as shown on the 1099-INT. If there is nothing in one of those boxes, leave it blank. What are you trying to do?
Do you have a 1099Int? From who? Your bank? The boxes on the screen should match the 1099 form. A bank 1099 should say the box # like box 1 and the amount. Only enter the boxes that have an amount. Leave the other boxes Blank.
