When did you file your 2018 and 2019 tax returns? Did you efile your 2019 return? The IRS will not schedule the stimulus payment until either your 2018 or 2019 tax return is completely processed. The IRS only started processing returns again on 4/26/20 after several weeks of not processing returns due to the virus and launching the stimulus payment so they must now catch up.
