When paying back HBP, do we need to fill-out the CRA form "5000-S7 Schedule 7 - RRSP" and send it by post, or does TurboTax take care of it?

When you fill out the RRSP & HBP sections in TurboTax, a Schedule 7 will be included as part of your return.

I filled out the HBP box 27 but it has taxed the withdrawal. It should be tax free for first time home buyers, what have I done wrong?

@Jon94 FDo you mean box 27 on your T4RSP? Then please go into the RRSP section and fill out the needed info for your RRSP contribution and your HBP repayment.
