The software was confusing when entering data. Areas where repeated and didn't make sense. Finally, it was rejected by the IRS twice when trying to enter electronically because my birthdate didn't match their records? What? It hasn't changed in 58 years...
I have been using this for years and too lazy to learn another one, but certainly the software is getting clumsier. It gets the job done, and I have never been audited, so there's that.
