Hi.
Open your .pdf document in PS (are you using CS). File > Open > <filename>
Select the text icon on the PS palette
View attachment 46296
Put the cursor onto your document and drag a rectabgle over the ? box that you are suppose to fill in.
Type your text, selecting the font, colour and size to fit (formatting palette)
When finished, click on the Pointer tool.
Adjust the position of the text box (fine adjustment by using the Up/Down arrow keys)
Repeat for the extra ? boxes that you have to fill in.
You will see that each extra text box that you create will be in an extra layer. Ignore those until the end of your text entries (but save your work periodically).
When you have finished, Layer > Merge Visible
The File > Save As
This is the way I would do it. Doubtless there are a squillion others and you will hear of those.
Get back if you have any problems.
