That might have solved other problems sooner had I spotted that. I realized I needed to make sure it saved with an ANSI encoding. However, during the process of using Notepad to add the header as described in the link from q.lurker, sometimes it defaulted to an Encoding of UTF-8 when I went to save the edited file. I was able to get that final 401(k) account to export and import when I broke it into smaller files.

Update (probably final one): I think I have reconstructed my Quicken file. Thanks.The QIF comment is generally misleading. Please tell me I am missing some reasonable solution here. Thus it appears that I need to go back to my files as of 8 months ago and roll all accounts and reconciliations forward to now or I need to start with the new file with the accounts I was able to import and add the (approx. The investment account transactions go back almost 20 years, so they cannot be downloaded from the brokerages themselves. So I have a corruption that appears to have been caused in the rollover process, none of tools that I know to be available to me can fix the corruption, and none of the options in Quicken allow for the export from one file and import into another file of transactions in investment accounts. Quicken help on QXF Exporting and Importing includes the following statements: "The import and export of investment and business accounts, transactions, budgets, attachments, reports, and application settings is not supported by QXF.If you need to import investment or business data, we recommend that you use QIF import instead." And then on the QIF page "QIF import is not available for checking, credit card, savings, 401(k), or any other brokerage accounts."
Update: The QXF route did not work, even with the accounts created.
