Is there a way to unfinalize my taxes? I may have been impatient and didn't wait for additional W-2s to arrive before filing, and now I'm worried I mess up on my taxes.

I worked for Home Depot and Walmart briefly during the beginning of 2020, but have yet to receive a W-2 for those work places. I'm worried I may have entered my tax info too early, and will either get too little for the work I've done this year, or will get in trouble with the IRS for a simple mistake. I was wondering if there was a quick way to redo my taxes so I can wait until my other W-2s arrive so I can make sure I get the proper tax refund.
