I finally got in touch with a TurboTax "tax expert" and they said to use the numbers from my actual return, schedule D, lines 7 and 15. It did fix the error and let me go on, although I believe it raised my tax due by just a bit. I really wish I had access to the AMT sheets to verify but I do not, since I did not file/pay AMT and TT did not generate that form in my package.
