Thanks for dropping your concern here in the thread, @Laura in RVA. Let us route you again to the support that can help you manage QuickBooks with MD Unemployment Insurance.

Since you have already added Intuit as a third-party agent with MD UI fund, QuickBooks should not generate notifications regarding "action required" or "file manually." Given that the status is active and ready to proceed, we recommend that you reach out to our support team for further assistance. Our support can provide detailed explanations as to why this issue is occurring on your end.

On the other hand, you may visit this link as guidance with managing payroll filings electronically inside QBO: Pay and file payroll taxes and forms electronically in QuickBooks Online Payroll.
