Thank you Area51, that did the trick. For anyone wondering how exactly to do it (free if you have 25 or fewer transactions like I did)...
1. Make an account at CoinTracker
2. Link your Coinbase (and if applicable, other exchanges) account.
3. Go to "Taxes" at the top.
4. Go to "Select Tax Plan" and select "Free" (again, only works if you've got 25 transactions or fewer... so TurboTax still needs to fix this to keep others from having to shell out to another company).
5. At the bottom right, there's a section labeled "Tax Reports." Click the tab "Tax Filing Software."
6. Next to "TurboTax Online File," click "Download."
7. Upload this to TurboTax, it should accept it directly.
Again, inexcusable those with more than 25 transactions have to pay a third party service when TurboTax and Coinbase both advertise interchangeability between their services, but... for those of you who, like me, do fewer big trades rather than many small trades, hopefully this takes some weight off your shoulders.
