Unable to file for extension using Turbotax

I'm following the instructions provided by Turbotax to file for extension:

 

https://ttlc.intuit.com/turbotax-support/en-us/help-article/internal-revenue-service/file-irs-extens...

 

After pressing "Jump to extend" I get the following error message:

 

"It looks this filing is not available

We are currently not accepting filings of this type."
