I had the same issue but was able to successfully Netfile eventually by modifying Schedule 6 in Turbo Tax. My solution likely won't apply to everyone but may help those who are in the same situation as my wife and I. For those of you where family net income exceeds the applicable limit such that you aren't eligible to claim a Canada Worker Benefit credit try going to "Forms>Schedule 6" and manually change the answer on line 38102 "are you claiming the basic CWB credit?" from "yes" to "no". Once I did that and saved the file I was able to successfully Netfile both my wife's and my returns. Despite having originally used Easy Steps and correctly answering all questions in our profiles, and double checking all forms for both our returns I was convinced the Netfile rejection error for my wife's return is a software error, either with TurboTax or CRA's Netfile. I then reviewed how Schedule 6 was completed for us in TurboTax2021 (neither of our returns was rejected) and determined that despite answering all profile questions the same way last year, line 38101 in Schedule 6 in 2021 was set to "no" (i.e. not claiming a credit) for both of us. I don't recall answering any profile question in either year asking if we wanted to claim the credit. So it appears (but I haven't been able to confirm 100%) that in 2021 Turbotax automatically determined we wouldn't claim the credit and indicated so on Schedule 6 but in 2022 Turbotax automatically determined that my wife would claim the credit and indicated so on her Schedule 6 (and the form appears to be completed correctly) but I would not. The only difference is my wife can claim the disability tax credit. Only my wife's initial 2022 return was rejected by Netfile (error 2226) until I manually revised her Schedule 6. Hope this helps at least some Turbotax users!
