If you are using TurboTax Online, there is no way to edit the forms directly. You'll be asked about the CWB in the Review part of the return.

I didn't get asked about the CWB benefit in the Review. I called Turbo Tax support and the

person I spoke to couldn't figure it out either.

In the Detailed Summary, is there an amount showing on Line 45300 for the Canada workers benefit (CWB)? You may also want to double check if you are eligible. This Canada Revenue Agency (CRA) has information on who is eligible for the Canada workers benefit (CWB):  https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-re...
