How can I enter US Savings Bond interest when TT will not create a field for Treasury?
If you are entering government bond interest, it will be either a 1099-INT with the interest in box 3 or 1099-DIV with box 12.
See another post of mine here with the steps and screen shots to enter your information.
1099-div box 12 is income exempt at the federal level like Muni Bonds. US Govt. Obligations would be reported in Box 1.
