late deposit of 401k contributions/late filing of form 5330

[Beemer]

A client held onto their 401k contributions from January through June 2010 and did not deposit the contributions until December 2010. The year ends June 30 and the Form 5330 was due January 31st, 2011, but will be late now. I am preparing two 5330's. On the first one, should I show interest up to June 30, 2010, and on the second return, show interest as on the first return, with another ltransaction for interest until the final correction?

Thanks for any help.
