Alright, I have figured out what was the problem. I cleared my return and started from scratch and I was able to successfully add the 1099-INT form. However, it turned out the Free version of Turbotax does not support foreign accounts. That was the reason why I couldn't file a return in the first place and not the incorrect message that I had an interest greater than $1500, whereas the actual interest was only $14. You should take action and make it clear for your Free product because eventually I bought a Deluxe version but spent several hours trying to figure out what's going on.
