On a 1099-INT.
On all of my 1099-INT forms, box 14 it is blank (entriely blank...no spaces...just empty), and I e-filed just fine, and received my Refund in 10 days.

IF it continues to give you trouble...delete the entire form and enter it manually...Do Not upload a Picture or PDF....enter it all manually....<<<"Enter Another Way<<"Type it in myself"
