where is my refund

I paper filed my taxes for 2020 and was due a refund. No word or deposit from the IRS. Have tried where is my refund and for months it said it was being processed now it tells me it can not find me in the system. Have tried calling the IRS about 100 times and cannot get to talk to anyone. If someone does answer they put you on hold and then comes on and says we are not taking any more calls today. Very frustrating. Now it is time to file again what do I do. Am I suppose to deduct last years refund on this years taxes. I am open to any suggestions. Thanks.
