I downloaded tax info from my 2017 H&R Block tax forms into the H&R block 2018 program. When I was ready to e-file, I found that I needed to edit the AGI amount by one dollar, so I went to Help Central (within the program). The pop up window said, go to the Edit menu or right click the field but neither action allow me to make the needed change. I have a MAC and maybe those instructions are for Windows users. I was eventually helped by an IRS support person who told me to click on "Forms" to make the needed changes to my AGI amount.
Pros: Easy to install, Maximizes refund, Easy to import, Fast
Would have given five stars but the ability to save as a P D F is tied to a third party provider, which did not work right. If I could have displayed the form in a browser I would have been able to do that quite easy. Very annoying!
