Read every question several times. I read them but because of my tax circumstances I answered one question wrong and it cost me several thousand dollars after IRS reviews. After the review Block gave my taxes the go ahead but they were wrong.
I have been using H&R Block software for as long as I can remember...and I'm 69. The 2020 version did not allow me to properly document the Inherited IRA funds that I rolled over in 2020 under the CARES Act provisions. As a result, I had to file a paper return with a letter of explanation, resulting in an 8 month IRS review period and a related delay in receiving our refund.
