Thanks for dropping by here in the Community, @cham04. I'll share some information about your concern.
If intuit files tax forms for you, these are available to view or print approximately 35 days after the end of the quarter. Amended forms are available once your case is complete. In case you've manually filed your Form 940, what you can do is run a payroll report and then filter the year to 2018. You'll then go to the IRS website to manually enter the details.
I'll be adding these articles for future reference:
Please feel free to get back to me if you need further assistance with this. I'll be more than willing to help you once again. Keep safe!
