"I read that submitting coding issues here in the Community can get a coding correction done by Intuit for ProSeries Professional?"

I'm curious where you read that, because that isn't accurate.  Once in awhile an Intuit employee will see something like that and forward it on, but for the most part, you need to contact support for something like that.

"There use to be an Intuit link where you could submit coding issues and they would get resolved"

I'm not sure where that was located because I have never run across it or seen a reference to it here and I've been here since about 1923.
