Hi, thank you for using Intuit ProFile Community

Jack_Canada has it right. CRA requires a date and time for electronically signed T183s. The taxpayer can sign and enter a date and time on the T183. When the signed document is received, the preparer enters the date and time on the T183 in the tax file to match the signed document. This will remove warnings from the T183.

If the question is answered no, then only the signing date is required so ProFile populates that field. 

Hope this helps
