There's really no way to know without printing your returns before and after and looking at them side by side. If you pay for Turbotax online, you don't have to file right away. You can go back and make changes, print different variations, and then transmit your return when you are satisfied. Or, you can install Turbotax on your own computer from a CD or download. You have to pay up front, but the desktop program allows you to view and print your forms at any time.
Assuming there is not a typo, it sounds like you became ineligible for some kind of credit because your income crossed a threshold, but it's hard to guess what that might be. Also possibly, the increase in income changed the taxability of social security benefits, if you are receiving benefits. If you have subsidized Marketplace insurance, additional income might change your eligibility for the subsidy. There are too many possibilities to guess.
