We left off the entity code on one investment on the Schedule D and the DOL wrote the client asking that it be corrected and an amended return be filed. Question - does the entire 5500, including all schedules, have to be sent in or can the client simply send in the 5500 stating it's amended and the revised Schedule D? Thanks for any assistance on this.

See page 6 of the 5500 Instructions:

Here is the section you need:

Section 4

Amended Return/Report

File an amended return/report to correct errors and/or omissions in a previously filed annual return/report for the 2001 plan year. The amended Form 5500 and any amended schedules must conform to the requirements in this How To File section.

The procedure for amending the return/report depends upon the type of form filed as specified below:

Paper Forms

Submit a completed, signed, and dated Form 5500 (be certain to check Box B(2)). Attach any schedules or attachments that are being changed from the prior filing. Do not attach schedules and attachments that are not being changed. Do not attach schedules where only attachments are being amended. Only identify schedules that are being amended on line 10 of Form 5500. If only attachments are being amended, do not identify any schedules on line 10 of Form 5500.

Electronic Forms

Submit a completed and dated Form 5500 with electronic signature (be certain to check box B(2)). Refile all schedules and attachments, including those that are not being amended. See the DOL Web site at www.efast.dol.gov for information on electronic filing of amended return/reports.

Note. If you are filing a corrected return/report in response to correspondence from PWBA regarding processing of your return/report, do not check Part I, box B(2) of the Form 5500.
