If your campaign had a carry forward amount from a previous campaign (candidate committee and single election year committee) or the previous calendar year (continuing committee), the amount will show on line 1. This is correct.

If you entered a contribution with a deposit date prior to the campaign start date, the deposit will be reported as a carry forward amount and appear on line 1 of the C4 instead of line 2.  Adjust either the campaign start date (File>Committee Info>Candidate) or the deposit date.
