It says invalid value under my bank's name for an imported interest input. What does that mean and how can it be corrected?

Don't enter the bank name and don't try to import it.  It is just as fast and easy to manually enter it.  At the bottom pick Change How I enter my Form

Then on the next screen pick I'll Type it in Myself

You shouldn't need to enter an EIN or address.  Just enter the name.
