Same thing happened with me I called the irs and she told me I need to amend my return because my numbers don’t match the numbers they have and once I amend they will realest my refund and then another lady told me don’t do anything for 60 days because they are reviewing it..I don’t know who to beleive because I’m scared that if I amend that I will need up owing and I’m scared if I don’t that I will never receive my refund
