If you have not already filed your tax return, then you should be able to go back to the "Personal" information section of the TurboTax program, and edit your taxpayer mailing address.
If you have filed your tax return, but yet haven't received a tax refund, then you can certainly change your mailing address of record with the IRS. In fact, the IRS maintains a webpage that will explain the various methods of effecting an address update. Here is the link to that page:

In addition, it may help you to know that this is a perfectly normal request you'd be making of the IRS. Taxpayers move and change their addresses all of the time. It's actually very common.

U.S. Postal Service doesn't offer mail delivery to your home's street
address.
Thank you for asking this question.
