The message probably just means you don't qualify for the Retirement Contribution Credit. The credit has a fairly low income phaseout.
In 2018 your adjusted gross income (AGI) also can’t be more than:
- $63,000 if married filing jointly
- $47,250 if head of household (with qualifying person)
- $31,500 if single, married filing separately, or qualifying widow(er) with dependent child
