The 170-character limit is only for the question title. There is a box lower down on the question form with room for a lot of details.
If you want to add details above, then just to the right of your question title above, click on EDIT. Then you will see a place to indicate the product you are using, as well as a box to add as many details as you want. This is a public Internet forum, so don't post any personal info.
This is mainly a user community forum though--not a direct route to TurboTax Support. We can tell you how to reach TurboTax Support by phone if you are using PLUS or higher.
