Why am I asked to enter a date that I placed an asset into service when I don't have an asset?

To clarify, you are not entering a business vehicle or machinery? 

Are you entering a rental property? 

No, I did not enter a business vehicle, machinery or rental property. I did not list an asset at all for this return or previous returns. I entered expenses for supplies only. 

You may have an errant asset in your program, you can remove it by following these steps:

Choose the Tax Tools option on your left menu bar while working on your return

2. Choose Tools

3. Choose the Delete a form option under Other Helpful links 

4. Find the Asset (wks) in the list and delete it

This worked, thank you!
