Used H&R Block/Tax Cut for years. Federal navigation has always been good. The Delaware State has improved but the back key takes you back to the last set of inputs or right to the beginning of the section (federal allocation) if you complete the section. It’d be nice to go back one step once the section is complete and the tax impact is updated vs right back to the section start.
I've used this software for at least 10-yrs, maybe 15. It used to be called Tax Cut. I've always been satisfied with the tax returns it generated, and I'm confident it works well.
