Where to enter retirement plan startup costs

[smallbiz103]

I recently established a 401k plan for my small business, and I believe I qualify for the corresponding tax credit (form 8881).  When I get to "Pension plan startup costs" in the section "Other Business Credits," I get an error that says "You have not entered any pension plan startup costs."  Where (under business income and expenses) do I enter those costs?

You must first enter the startup cost as a business expense under All other expenses (where all expenses other than vehicle expenses, depreciation and home office expenses are entered).

Thanks for trying to help!  I don't see a category labeled "All other expenses" (I'm on the Mac desktop version if it matters), but I do have "Other Common Business Expenses," which appears between "Business Vehicle Expenses" and "Home Office Expenses" under "Business Expenses" (depreciation seems to go under "Business Assets," which is right below "Business Expenses").  Anyway, "Other Common Business Expenses" leads to a page with 16 subcategories:

1. Advertising
2. Business Travel
3. Commissions
4. Communication
5. Contract Labor
6. Insurance Payments
7. Interest Payments
8. Legal and Professional Fees
9. Meals
10. Office Expenses
11. Rental Expenses
12. Repairs and Maintenance
13. Supplies
14. Taxes and Licenses
15. Utilities
16. Other Miscellaneous Expenses

Under the last category -- "Other Miscellaneous Expenses" -- one of the examples is "Pension plan administrative costs (not contributions)," which sounds promising.  However, the "Other Miscellaneous Expenses" page only has spaces for "Description" and "Amount."  I've tried a few different descriptions (like "Pension plan startup costs" and "Pension plan administrative costs"), but when I then go to "Other Business Credits" and to "Pension plan startup costs," I still get the same error message, namely, "You have not entered any pension plan startup costs."  Am I entering my expense in the wrong category?  Or am I using the wrong description?  Thanks again!

If you are using TurboTax Home & Business, TurboTax won't present the option to enter Employee Expenses where you would enter plan startup costs.  To qualify for this deduction or credit, you must have employees (other than yourself as self-employed), indicated in the Business Profile.

I was able to do this by working it backward from form 8881.  Create and open 8881 up in the "forms" section. Up top on the form it has a box that links to Sched C, F or form 4835 depending on what type of business you operate.  I clicked on the Sched C box (sole proprietor) and then hit QuickZoom to go to that form.  There I was able to enter my startup costs, as well as claim a $500 credit for creating a 401k with a automatic enrollment option with the plan.   It places the qualified startup costs automatically into the business expense form.  

Note that Turbotax program the finalized 8881 will not be available for e-filing until 3/6/2024
