Hi, RC. (Love that name!)
You shouldn't enter it in YOUR books at all, because it isn't YOUR income.
I've never had an IRA, 401(k) or similar plan, and have never used Quicken to account for one, even for a client. But I was in practice when Congressman Keogh got Congress to pass the first of such retirement plans back in the 1960s. These plans were invented to allow self-employed individuals to get tax benefits similar to those enjoyed only by employees whose employers established retirement plans.
The essential theory in all these plans is that a TRUST is created. Money is contributed to the Trust and no longer belongs to the contributor. It is technically owned by the Trustee, who has a fiduciary duty to manage it, in accordance with the Trust agreement, for the benefit of the beneficiary - the future retiree. So, while the beneficiary has a strong interest in what happens to the funds in the Trust, that money does not belong to the beneficiary until it is paid out of the Trust to him, at retirement (or early termination of the Trust). The beneficiary's income statement should not reflect any transactions or growth in the Trust, except maybe by a footnote. And the beneficiary's balance sheet should not include the balance in the Trust - again, except in a footnote.
As I said, I've never used Quicken for such a plan, but I THINK it should be in a separate Quicken "file" - actually a set of related files - established for the Trust by the Trustee. All that should show up in YOUR Quicken file should be contributions from your checking account, or via payroll deductions, to the Trustee - and the eventual retirement checks coming from the Trust. The Trust's file should reflect receipt of the contributions, plus all income, expenses and other transactions by the Trustee, including eventual pension payouts.
I know that most IRA beneficiaries ignore the legal niceties of all this theory. As I said, I've never used Quicken to account for such a plan, so I don't know how Quicken deals with blurring the lines between the employee and the Trustee. I'll let others tell you how, in practical terms, to handle these retirement plans. I haven't even bothered to read Quicken's Help file about this; have you?
Remember that I've been retired for over a dozen years, so be sure to check all this with your own CPA, who should be familiar with the current rules - and might be familiar with Quicken, too.
