One of Turbotax's technicians showed be how to completely delete Turbotax from my computer (https://ttlc.intuit.com/turbotax-support/en-us/help-article/diagnostics/forcefully-uninstall-turbota...) and then had me reinstall from my CD. That didn't work, however, by deleting Turbotax and then downloading from Intuit, that did the trick.
