Also love Turbotax and have used for 10+ years. Vanguard will give it to you free/reduced rate depending on how much you have invested with them. Our taxes are quite complex but the program has had no issues with them.
It seems to me that the hardest part of doing your taxes is gathering together all of the paperwork, receipts, etc. And you have to do that whether you use a CPA or do it yourself. So why not just do it yourself.
If any issues come up, there is a huge user community to provide answers to your questions.
