@Richard67 Click the "Discuss" button at the top of the screen and then click on one of the boxes that relates to your question (e.g., "Taxes").

thank you

 I did not see a posting dialog box or any mechanism after I clicked the box ( tax). Very frustrating 

1.  Click "Discuss" tab at the top of the page

2.  Click in one of the areas that relates to your question "Taxes" for example

3.  Click in one of the areas that relates to your question "Deductions and Credits" for example

4.  Click "Search a question" or "Ask a question"  and dialog

For some reason, I can’t find how to post on the site. But can only reply to someone’s post. Any tips will be appreciated.
