Been using TurboTax for years. Switched it up a few years back and regretted it, so came back to TurboTax and have had no issues since. Hopefully it stays that way!
I had a great experience on turbotax until when I was finished with my return and it made me pay $132 in fees or I would not be able to continue with my tax return process. This was never mentioned throughout the whole process until I was ready to submit.
