Deductions & credits

Thank you for your detailed description of the work-around for the bug I described; I’m sure other people will find it helpful when then encounter the same bug (and with the majority of people now using the Standard Deduction, I’m sure there will be a lot).  That being said… my question wasn’t how I could work around the bug (I had already figured something out that worked, and in fact, had already e-filed my return), my question was how can I submit a “bug report” so that the developers can fix the bug.  I still can’t find a viable way to do that… other than a post here, or on Facebook, etc., none of which are setup for “bug reporting.”
