Since this In-plan Roth Rollover includes after-tax money that had been in the traditional 401(k) account, the amount in box 2a cannot be the same as the amount in box 1. Only the taxable (pre-tax) portion will be in box 2a and the after-tax portion should be in box 5.

Actually the amounts in box 1 and 2a are different. The gross distribution in box 1 is considerably higher than the taxable amount in 2a. Fidelity explained that since these were after-tax contributions I just have to pay tax on the smaller amount in box 2a.
