Your post indicates you're using TurboTax Online, but that's not always correct. If you're using TurboTax Desktop on a Mac, this is a known issue.
See the TurboTax Help article Why am I getting an error when trying to enter the address for the home where I installed the energy efficient property? for guidance.
If you're actually using TurboTax Online, describe (or post a screenshot) of the screen you're seeing.
I am using TT Desktop for MAC.
I finally went directly to Form 5695 to enter my address.
I was able to continue after that.
Thank you

Click on the Forms icon in the TurboTax Menu. When in Forms mode locate the Form 5695 and click to open. Enter the address on the form.
