The "Where's My Refund" tool is no longer active for 2019 returns, so it won't show you information about that return.
You will need to call the IRS, and they will need to give you more information. You can reach them at [phone number removed]. It is likely that your return is one of the millions of 2019 returns that the IRS has not finished processing and it is likely that they need additional information to complete the return.
Unfortunately, if your income is too high in 2020 to be eligible for the recovery rebate credit, and you weren't sent any of the first two rounds of Economic Impact Payments, you will not be able to recover those. Since the income threshold is even lower for the third payment, I can't imagine how you will qualify for that one either - however, if you believe your 2019 income would qualify, file an extension for 2020 and wait to see if they will process that payment after they process your 2019 tax return.
