Retirement tax questions

I'm confused, too.  I am in the same situation. 
One of the first Income questions is:  Are you a beneficiary of an RRSP?   I thought that meant, did I inherit an RRSP?  but I filled it out anyways because it asks for detail.  And, I completed the info (e.g. 10,000 total withdrawal and 7,500 taxable (which I don't understand) but then my total income tax owed went sky-high and I couldn't figure out how to tell TurboTax that Canada has already deducted 25% tax so I shouldn't be charged.  Then I changed the "taxable amount" to $0 but I know this can't be right...
