Here is my issue, example. Box 14: $13Box 15: $13And box 18: $6 Should box 15 actually be $7 or should box 14 be $19?

On which slip?

It is on my T4E

Box 14 should probably be $19. But if you slip is showing incorrect amounts, you’ll need to contact Service Canada to get a corrected slip: https://www.canada.ca/en/employment-social-development/corporate/contact/ei-individual.html
