Can not download tax documents from Interactive Brokers. Many Financial Institutions you can, but it is an inconvenience if you have an account with IBKR.
I've used this product for many years, and I haven't been audited. Yet. It's fairly easy to use, and I got a special price this year. It's typically cheaper than Turbo Tax anyway. There are still a few bugs. When I download tax data directly from Fidelity, it asks me to verify hundreds of fund names/# shares on trades manually, which is annoying. One would think the file formats, etc., from brokerages would have been figured out after all these years. These verifications are done during the Accuracy Review. They say you can "clear" the warnings and errors, but in my case that was not possible. I clicked through and accepted all the warnings, but they weren't cleared. Every time an accuracy review was done, the same warnings remained and couldn't be overridden. This is a poor user experience. You should be able to validate that the trades are acceptable one time and then move on. Also, the Accuracy Review window remains open after you finish, and you somewhat lose your place in the main flow at that point.
We've used H&R Block software for decades. The software guides you through everything very carefully, and we especially appreciate the 1099 import feature where you can import all your capital gains/losses automatically. Wonder feature and make everything very easy.
Pros: Easy to prepare, Maximizes refund, Easy to import documents
