Iv'e been using H and R Block, previously known as Taxcut, for years. It is easy to use. The only problem I had with it this year, it would not allow me to make a payment with a date after 4/15/19. I live in Massachusetts and we have until 4/17/19 due to a Mass. state holiday on the 15th and a Wash. DC holiday on the 16th.
I have used a different tax prep software for years. It's straight forward, picks up where you leave off, double checks for mistakes and has a great printout for your records. H&R block was ok. It's 1/3 of the price of the other software, it doesn't open to where you left off and the forms for worksheets and state are, well, sloppy. I think next year I'll just use federal and efile state based on this first impression with H&R Block. Just ok. The other problem I encountered was importing other financial information. But... it was cheap.
