I am having T3 Errors with boxes 21 52 and 53 on 2 returns

[Golam]

For all T3 slips in your return: - Remove the amount from Box 52, if applicable (leave it blank) - Enter the sum of Box 52 + Box 53 in Box 53 - Ensure Box 53 equals the amount in Box 21 If the error persists, try rounding the box amounts (21 and 53) to the nearest dollar and submit via NETFILE once more.
