"1. A table that gives a description for the data contained in each field."

You may be interested in the files, where you have Lacerte installed:
   "C:\Lacerte\18tax\MOD\usdbdef.?##"

(There is a file in each module's directory; use three-letter MODule [ind, par, sco, gif, whatever] in that path, and the letter in the extension varies by module [p, s, n, whatever]; last two digits of the extension are the tax year being done.)

I use these column headers (column letter, text):
COL  USAGE
  a   FILE
  b   Field
  c   Long Name
  d   Short Title
  e   Field Type
  f   Field Size
  p   Toggle Type
  q   Info Type

Bring that document into your spreadsheet, add the row of column headers, and you will find much made clear to you.
