After you file

Filed and accepted 1/27/20. No letters at all. Called and spoke to IRS agent 3/15/20. He stated NOTHING wrong, no red flags, no additional information required. Must be patient. ETA ballpark he said would be last week of April to the first week of May. Still nothing. It has been saying this since first week of Feb. "We have received your tax return and it is being processed." So there is something wrong and the agent lied to me?
