T183 - Resending for signature

Newer Tax Cycle user here. I use DocuSign for the T183s as well. I’m having trouble trying to resend the T183 after it has been signed and then I needed to change the name. In particular CRA is not recognizing the name of a first time filer and I’ve changed the name to agree to SIN card. I can’t see where to delete the incorrect T183 currently attached to the return and start over. Thanks for any help!
