Just wondering if I need to report the regular monthly deduction by Primerica, or if it asks about ADDITIONAL ones?
No, a retirement savings contribution credit is a credit against your federal income tax for contributing to a retirement account. Depending on your income, if you make contributions to a retirement account during the year and meet other requirements you can get a reduction in your income tax in the form of a credit.
Ok..... so, the standard monthly amount my Roth IRA takes out of my bank statement is NOT considered "contribution" to a retirement account here?
It is a contribution that may afford you a credit. The credit would be called a retirement savings contribution credit. But the contribution would be just that, a contribution, not a credit. You may not qualify for the credit just because you make a retirement contribution. Also, the credit would be less than the contributions you make.
