State tax filing

So, I think I forgot to sign my tax return. I call and call to see what would be the next steps, they direct me to “where’s my refund,” which is NOT at all helpful. I look on the website to see what it says. “The IRS will get back to you once they’ve received your tax return.” It’s been 5 months and I haven’t gotten a response or my tax return. What am I supposed to do?
