Hello there, @vcgspangel2.
This message refers to the availability of the second Quarterly Form 941.
The quarterly form 941 is not yet accessible in QuickBooks Online. We're still waiting for the finalized form from the IRS to ensure the accuracy of the information. This includes the additional entries from the Families First Coronavirus Response and Coronavirus Aid, Relief, and Economic Security Acts which added many types of payroll tax relief.
To know about the updates, I recommend bookmarking this article: Forms unavailable (blocked) - Federal and State Forms.
Should you want to submit your quarterly form 941, I suggest filing it manually to IRS.
You are always welcome to post in the comment section below if you have other concerns or questions. Have a wonderful day ahead.
