Can I still file 941s for 2019, and if so, how?

Hi there, @lawofficeofhk.

The 941 form available in QuickBooks is for the year 2020. You'll want to download the prior form on the IRS website. Then, manually enter the information by checking out the tax reports in your QuickBooks Self-Employed (QBSE) account.

Here's how to download your 2019 Tax report:

1. In your QBSE account, go to the Reports menu.
2. Click on the Tax Year button along the Tax Summary or Tax details.
3. Select Download or click the Print/ Share icon.

I added a screenshot for additional reference.

Once you're done with entering it manually, you can send it to IRS right away.

Loop me in if you need anything else. I'll be here to help. Stay safe.
