If you e-filed then there will be an electronic postmark with the pdf you saved. If you mailed it.....nope, unless you have a receipt from certified mail, etc. showing that it was mailed.
And....why? Is the IRS saying you did not file a return? Or are you having to prove it to a lender, etc.? Who wants the proof?
Or do they say that you did not pay your tax due? Your only proof that you paid would be your own bank or credit card record.
Or.....look for a transcript or look at your IRS online account.
