I've used this program for about 10 years now. It seems to get easier every year. In the past few years I've had no questions and was able to finish my taxes with no problems. I find gathering the data to enter takes the most time, and I'd have to gather that data no matter who or how my taxes are done.
Estimated tax for the state of California was added TWICE to the total Stste tax withheld. It cause the state tax e-file to be rejected! I filed it manually. It took over 5 weeks to get processed! - BAD!!!
