Point of Contact for Apparent Program Error? (Maryland State)

Using TTax Deluxe.  For Maryland Form 502 on the two-income subtraction worksheet, believe there is an error in how TTax aligns the entries between taxpayer and spouse (from Sched B items) on line 11 of the "interest and dividends from US obligations" on that worksheet)   Have gone back and rechecked all applicable inputs (including the  taxpayer vs spouse assignment check-off on individual Sched B entries) and have manually tabulated those inputs, and line 11 of the two-income subtraction worksheet clearly does not accurately reflect the proper results for "interest and dividends from US obligations" (total OK but taxpayer and spouse breakout faulty).  Haven't looked at prior years in the same detail, but a glance at the same form in a recent prior year superficially suggests this is likely an issue in prior years as well.  While this misalignment results in errors on line 5 of Part II of the two-income subtraction worksheet, so long as columns of line 5 are $1,200 or more, the final result on line 7 will not be affected (probably the usual case).
