Yeah, software changes. Generally validation is considered good, but this might need some reconsideration. Of course, I always advise that people with 100s of transactions (especially complex ones) should probably NOT use the automatic import. Instead, in these situations I recommend summary entries supported by attaching the actual data from the brokerage.
This alternative is not immediately obvious in the interview. The actual number of people doing many complex transactions and self-filing using TT is probably a small percentage of filers, but it's also probably more common now than it has ever been in the past.
