Hi, I’m a new EFPS volunteering taxpayer. How do I attach Form 2307 to my 1701Q for this quarter? The company only gave me a generated PDF copy of the form.

Do you have any template that I can use for this?

Also when I try to upload the file, I always get the same error: The file you wish to attach to this return does not conform to the standard file naming convention. What is the correct way of naming attachments?

I searched online, but I couldn’t find the answer. The EFPS website doesn’t help at all.
