Let me clarify:
Season Ticket holders CAN list their seats on Ticket Exchange for ALL games right now. They have opened that for ALL 19 home games from start of season.
For Transfers to Friend and Family, ST holders can do that for games till end of October. Each time TV picks get announced for a month (next will be November fixtures) a day or two after that you will get an email from City saying you can now manage that month's fixtures.
The emails with a link to mobile ticket to those who you transfer to normally comes within a week to go of that fixture. But having said that, I have already received emails for such for games all the way to Fulham already (only Saints left, till end of Oct).
Ipswich should be open for transfer right now and when you transfer the recipient should receive an email straight away. If you can't do that, give the club a call.
