I see a charge on my back account from Kohl's I don't remember. I don't have a receipt for the purchase, can someone help me find out if this is a bogus charge?

Call kohl's and ask what it is

Your bank should be able to tell you if that was paid by paper check or if it was your debit card, after you find out what method of payment was use and you don't think it was you call khols and tell them what happened and what the payment method was most likely they will try to help you out . Good luck.

Try and dispute it with your bank and see what happens.
