Divorced tax issues

Hi I’m stressed and confused.me and my ex are still on good terms and we still pay on a payment plan of taxes we owed when married

i just filed my now single taxes today and I owe..I guess I wasn’t having enough withheld from my check during the year lol.I requested a payment plan to pay and didn’t think about it but are they going to deny me a payment plan since I’m still on one with my ex from when we were married and joint? 😞 neither him or I can afford to fully pay off that payment plan right now and I cannot afford to straight up pay in full what I owe for my own taxes right now either so what is going to happen?
