Last name misspell paper pass

I misspelled my last name on my paper pass Struckman when it is actually spelled Struckmann. Can I still travel if it’s misspelled by one letter but all of the other information is correct? So then I don’t have to exchange and pay the fee? We also misspelled his name on the seat reservations and would have to pay extra fees to fix those too. If the pass and seat reservations match (misspelled by one letter) is it okay?
