Hi Critter#2. Thanks for re-joining the discussion. For each page of Form 8949, line 1, there are 14 rows for trades. However, for Form 4797, there are exactly 4 rows for line 10. The special instructions (located on page 8 <a rel="nofollow" target="_blank" href="
https://www.irs.gov/pub/irs-pdf/i4797.pdf">https://www.irs.gov/pub/irs-pdf/i4797.pdf</a>) for traders who choose Sec 475 MTM Election say this: "Attach to your tax return a statement, using the same format as line 10, showing the details of each transaction. Separately show and identify securities or commodities held and marked to market at the end of the year. On line 10, enter 'Trader—see attached' in column (a) and the totals from the statement in columns (d), (f), and (g). Also, see the instructions for line 1, earlier." There is no mention of a "summary entry." So, I am not sure what it is that you are calling a summary entry, and how it relates to the special instructions. Could you clarify?
