After you file

The IRS hasn't processed my original return. They need a signature (I'm a dummy lol) and some proof of my income even though I don't receive a 1099. The "proof" I pulled, my PayPal transaction history, is a couple hundred dollars off from the reported income on my original return. 

 

Should I send the PayPal info and wait for the IRS to tell me to amend?

 

Line 18 is my original return, but it has not been paid to me. Line 22 and 16 is 0, but Line 20 has an amount due. Line 18 is more than Line 20, so I'm not sure how much I owe or am due. Haven't dealt with a 1040V yet. Thank you @rjs for your help!
