I've used H&R Block tax software for years. It has always been easy to use and produced accurate results, both federal and state. In addition to the usual annual tax filing, the section to prepare an amended return is also very easy to use should the need arise.
Pros: Easy to prepare, Easy to import documents, Fast
Although it worked well in 2020, last year I could not download financial data from Charles Schwab or TIAA. That made it tedious to use the software. Apparently TurboTax DID allow the download. Otherwise, the program is pretty simple to use and helpful. Please fix the download issue...or I will not be back.
I strongly recommend this software for calculating and submitting taxes. If you are using a competitor's software package, I would suggest trying it one year just to see.
