I just reviewed this thread. NotSuzy is right. Turbo should keep carryovers according to Social Security number(s). The comments that it is up to the customer to make sure everything is correct misses the point.
Carryovers are the one thing you have to separately remember for an entire year after filing your return. All the other important income and gains or losses for the current tax year are specifically asked for, and the TT customer is mailed forms during tax season. Even charitable contributions send receipts, plus this is something you do throughout the year. This has happened to me and family members before, and I had to file amended returns. So now I write an email to myself and have it timed to be sent the following January to pay attention to carryovers. This should not be necessary.
