If your data is rejected for a date of birth and Social Security number mismatch, but you KNOW the information you have entered is correct, then the problem is likely to be in the Social Security database, which is what the IRS uses to compare your dependent information to in order to ensure you are claiming legitimate exemptions.
It is recommended that you contact Social Security to resolve this, as no matter where you go to file your return, the problem will persist if the Social Security database is incorrect. Their website is https://www.ssa.gov/
You do not appear to be receiving a name mismatch error, but in general, it is best only to use first and last names.
