Tax exempt non-covered non-resident state obligations OID

I have a tax exempt non resident state bond I purchased in 2014 and is due in 2027.  There is no yearly fixed income reported on my 1099.  Should I pay the yearly  unofficial OID that is informally reported yearly as an addition to my state tax or wait until it matures?  Since it is state taxable, I do not know what to do. Will this affect the cost basis of the bond at maturity?
