I found a small error the way your 2019 download software works.
I entered a Wells Fargo Brokerage 1099-INT with $0.02 of taxable interest in box 1, and $10.69 of "Bond Premium on Tax-Exempt Bond" in box 13. There are no other items for this somewhat unusual 1099-INT.
Your software rounded box 1 to $0, and box 13 to $11, as expected.
Your software then would note the 1099-INT as failing to pass validity checks because of the $0 in box 1 that could not be offset by the bond premium.
One way I found to work around this was to put $1 in as taxable or non-taxable interest and then it would pass validity checks. The other way was to simply not enter the perfectly valid 1099-Int. This is also known as lying on a federal tax return in order to get the software to work.
I have been using H&R Block software for close to 20 years. I have always found it easy to use and very reliable. It takes the drudgery out of tax time.
Pros: Easy to prepare, Easy to import documents, Fast
Very easy to use. Can complete your taxes as source documents come in and not overlook any item or deduction. As a loyal user for many years I have confidence of the accuracy of my return.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
I "upgraded" from Turbo-Tax to HRB several years ago and happy that I've done so. Since I don't own a business or have rental properties, the basic version works perfect for me. I have never had a problem and it is simple to use. When I submit my return, I have complete confidence that it is error free.
