Get your taxes done using TurboTax

Look at the top of your Form 5695 to see if the first box is checked.  If you're using TurboTax Desktop and can open Form 5695, uncheck that box if you're filing as Single, as well as the box you indicate in your screenshot, if it's still checked. 

If you're using TurboTax Online, close the program, clear your Cache and Cookies, and return to the Home Energy Credit section.  After indicating that you made energy improvements, you'll see a question asking about 'living arrangements'.  Make sure you didn't indicate you shared the home with anyone else.

This may resolve your issue and allow you to Efile without error.  If not, you'll have to wait until the IRS resolves this issue.
