Yes, box 5 of Form 1099-R is amounts that are included in box 1, but are not taxable either because it represents your after tax contributions (basis), or amounts paid for your health insurance coverage (usually only on a pension). This includes Roth contributions.
Code 1B in box 7 represents an early distribution from a Roth account. If you have no number in box 1 or 2a, I don't know why they would issue the 1099-R at all. It will not impact your return unless there is a number in box 1 or 2a.
