In TurboTax Online (DIY), ReFILE is not available for Quebec residents. To ReFile, Request for an Adjustment to an Income Tax Return

Schedule S is specifically for the "Amount for Post-Secondary Studies" (which corresponds to Box A of the RL-8). This is a fixed amount per term (usually around $3,800+ per term) that a student can transfer to a parent to reduce the parent's Quebec tax.
Entering a T2202 only handles the Federal Tuition Credit (Schedule 11) and the Quebec Tuition Credit (Schedule T). It does not cover the specific Quebec "Post-Secondary Amount" (Schedule S).
To generate Schedule S and allow the transfer of that amount to you, your son needs to:
He must go to the "Federal Slips" or "Quebec Slips" section and find the RL-8 entry screen.
Enter the number of terms and the amount shown in Box A.
Once the RL-8 is entered, TurboTax will prompt him in the "Deductions & Credits" > "Students" section to complete Schedule S. He must explicitly indicate that he wishes to transfer the funds to a parent (and enter your name/SIN if prompted).
We replicated the scenario on our end and found no issues. Since the return has already been filed, the only option is to wait for the Notice of Assessment and then resubmit it to Revenue Quebec.
