You have to do it manually 

Just tried to go to forms, then netfile.  As suggested by one of the community members.  Still doesn’t allow me to netfile with the same message about errors in box 52 and 53. Needing to be fixed

this is getting a bit ridiculous! Can turbor

tax resolve this ASAP?

@Yuich 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. Try filing after April 7, 2025.

Expected resolution date: The CRA updated on April 16, 2025 relays that additional variations of this error clue setting incorrectly are expected to be resolved on April 23, 2025.
