Each Review section may be different depending on what items the program has identified that the user needs to change or complete.
You should be able to go back and revisit any section in the program all the way up until just BEFORE you press the button to e-file your return.
If you are referring to the decline/accept answer to the the "Do more with your data" and "Share your data with Intuit" questions, you have the option to send an email to privacy@intuit.com and mention that you'd like to change your “consent for use of tax return information" if that is the case. Or, you could see this help article and this one for instructions on how to contact TurboTax customer support depending on which product you are using.
