Thank you for the troubleshooting suggestions. I have tried everything you have suggested, to no avail. [I have been trying everything I can think of over the past 3-4 weeks.]
Here is a practice case (home address = PA):
Box 1a = $285
Box 1b = $0
Box 2a = $0
U.S. Government interest = $103
Thanks again.
PS: I also have tried every permutation of entering $0 and/or leaving the boxes blank (and/or using fake values greater than $0 as a test).
