If using Online TurboTax, the option to receive a refund by paper check is in the FILE section. It's on Step 2 where it should show you the options to receive a Federal refund.
NOTE: You cannot get a paper check if you chose to pay your TurboTax fees out of your Federal refund. That option requires direct deposit.
Is your product charging you for "LIVE Basic"?--at least that is what is showing underneath your question. If that's correct, is that the product you want to be in? Are you sure you want to be using a paid product instead of using Free Edition (if you qualify)? Live Basic is an upgrade from Free Edition that has an added fee for access to a tax expert to help you on-demand during return preparation and a final review of your return prior to filing, if desired. Did you use or want that service? If you do not want it and haven't used it, it can be removed prior to filing. See the FAQ below:
