Assuming that is the only issue stopping you from e-filing, it is hard to be sure why the program won't accept "Var" or "Various" in Box 14 of 1099-INT.
The IRS updates its e-file filters and rules every year; what may have worked in the past may not work this year (many posts on this issue). When the IRS updates its e-file filters and rules, TurboTax has to do the same.
Try leaving Box 14 blank - it won't affect your taxes at all (you may have to delete the Form 1099-INT and re-enter it). See: How
do I delete forms in TurboTax Online?
