You'll often find answers built right into the tax preparation software: look for a button on the page where you're having trouble to click for explanations and additional info. If you'd like to get help from a tax professional, you might be able to connect with someone by phone or online (though that may incur extra charges). A few tax prep software providers have in-person options if you get stuck and want a tax preparer to take over or just want to go over your return face-to-face.
