Checking the IRS site … no record found can be shown from time to time even if you enter everything correctly and this is normal. I will also be this way if you try unsuccessfully too many times in a row … then you are locked out for a day.

If you mailed in the return then it will not show up on the IRS site until the envelope is opened and the return is manually entered into the system which could take months as the IRS is understaffed again this year. Mailed in returns could take 6 months to a year to process and there is nothing you can do to speed it up.
