How do I know what pages to send on my amended return?

[sanj720800]

There are 192 pages including work pages. Header shows $466 refund due to me. Some pages show overpayment due, other pages show additional tax due.

You will send the 1040X and any other forms/schedules that changed from the original filing but NOT the old or new 1040 in the tax file.   Look at the form 1040X column B ... you must send all information that supports the changed made.

I'm sorry, I was not clear in asking my question.  I am unsure what forms to send to my STATE (Illinois) (not Federal).  I have pages that show I am due a refund of $466 but another page shows I owe $106 in tax.

In the PDF file of the state return to be filed there should be instructions on how/what/where to file the IL amended return.  

Here are the instructions from IL :   https://www2.illinois.gov/rev/forms/incometax/Documents/currentyear/individual/il-1040-x-instr.pdf
