Like many here, I've been unable to get the IRS retrieval tool to work. I filed my taxes over a month ago. I called the IRA, took about an hour while I was routed around. Spoke to someone at their tech support help desk. They were basically clueless--hadn't even heard of the tool--and they elevated the case. Somebody will supposedly call me back.
Then, I called the college my daughter will attend (should have done that first), and the woman immediately asked me if I had set up my e-filing so I would remit the taxes owed sometime after I filed.
BINGO. My tax payment just went through today. She said that the tool won't work until you have done everything relative to your taxes including making required payments.
She added I should be able to use the tool about two weeks after my taxes are paid. The same holds true for going to your local IRS office and getting an official transcript.
I'll see in two weeks. Fortunately, I have a May 1 deadline.
