How can I get a 2016 payment plan when I had one in 2015. I paid the 2015 off Sept 2017. IRS says I can't have another payment plan within 5 years. Can't pay without one.

Your other option is to just make payments ... every month when the IRS sends a bill you can send a payment. 

Or try mailing in the form 9465 ... see the IRS info on this option ...  https://www.irs.gov/payments/payment-plans-installment-agreements
