Thankyou for clarifying that! This is helpful. Relieved to know that Pro Connect is doing the right thing by adding the interest from box 3 over and above the $5100 on the federal return - Sch B. I didn't have the instruction for this  particular f1099Int as the client did not upload it, but I did check the IRS website for the instructions, it was not very clear on how the federal should treat the box 3 amount. State being non taxable, I was aware of that. My concern was only on the federal Sch B, it if was correct to increase the $5,100 by the US obligation amount given on Box 3. Have a great weekend!
