If your 1099-R has box 2a (taxable amount) empty and box 2B (taxable amount not determined) checked, it means the payer didn't calculate the taxable amount. You need to determine it yourself. If the entire distribution is taxable, use the amount in box 1 (gross distribution). If only part is taxable, calculate the taxable portion.
TurboTax will guide you through this process by asking additional questions. For more details, check here.
