Withdrawing and repaying ROTH IRA contributions tax and penalty free Is it correct that I can repay withdrawn ROTH IRA contributions tax and penalty free as long as I do it within 60 days? Is there any way to lengthen this window?

Is it correct that I can repay withdrawn ROTH IRA contributions tax and penalty free as long as I do it within 60 days? Is there any way to lengthen this window? We are in the middle of a remodel and costs have nearly doubled from the estimate since we began. We just need time to build our funds back up but don't want to lose any part of our tax sheltered money.
