How do I claim direct pension contributions (while on maternity leave as well as lump sum pension buyback) not reflected on a T4?

In Turbo Tax Desktop software, use the RRSP section found in the left hand menu of Easy Steps. Select the "RPP Past Service Contribution" option and then proceed to provide the required information. The deduction will transfer to Line 207 of the tax return.

Need to know where to enter the receipt for maternity leave pension that I bought back.
