Your QPP or QPIP contributions on your Relevé 1 slip (box B, box B1 or box H) are different than the amounts reported on your T4 slip (boxes 16 and 17, or box 55)

Error: Your QPP or QPIP contributions on your Relevé 1 slip (box B, box B1 or box H) are different than the amounts reported on your T4 slip (boxes 16 and 17, or box 55). These amounts transfer automatically from your T4 to your Relevé 1, and should be identical. If you entered them again manually, edit your Relevé 1 slips to remove the duplicate amounts.

But i do not have B1 and 16 is empty.

B /17 and H/55 has the same data
