Yeh that is fine to import dead last if you don't have 5 different brokerages with thousands of transactions... haha, even just one of them causes endless hours of spinning that never works.
call support and they just claim they never seen it, I finally solved the issue for years now, by never importing and just simply entering in transaction totals like your second suggestion.
I think importing is fine for someone with only a few transactions in their brokerage accounts over the past year, but when You have hundreds of pages of transactions, the import feature is not smart enough to resort to just totals and tries to import every single transaction.
I did try your first idea many times, but it just never worked for me, because just the tax review even would spin indefinately and eventually time out after 30 minutes or so and send a failure message and blame it on my high speed internet being to slow... LMAO. Even call in to support and their first claim is your internet must be to slow... LOL... even when you have super high speed interenet...
But entering the totals will work everytime, so I just manually enter everything. You have to do that anyway if you want to claim US Government dividend write off. That info you have to calculate by hand, import never takes care of that right off, for instance government bonds, are TAX free at the federal level or ETFs that are mostly based on tax free bonds, if you don't hand calculate the right off and enter it, the import will not give you the tax break you deserve.
