Hi, I had submitted my tax return on April 9th and it still says pending after 48 hours? Will I get in trouble with the IRS if it says pending if it's past the deadline?

I couldn't get my W-2 from my crappy employer for a long time after he shut down his business. I just got my form 4 days ago and I have submitted my return but it's been over 3 days since, and it still says pending. I am terrified that it won't go through and that I could get into a huge legal battle because of it. I've tried contacting the IRS but since I get a robot and not a person, they won't help me figure out what to do from here. Does anyone else have this issue? Or does anyone know how I can resolve this?
