Did you file by mail? Do not e-file now. You already filed your tax return. The IRS is severely backlogged this year. It's taking 6 months or more for mailed tax returns to be processed. And the information on irs.gov is not necessarily up-to-date. They have said that they hope to clear the backlog by the end of this year (2022).
Filing another tax return will only cause more problems and delays. There is nothing you can do but wait.
