Business & farm

Why doesn't TurboTax generate form 4562 to be sent to the IRS? TurboTax calculated how much depreciation I could take this year and entered it on schedule C but didn't create form 4562. Is that because I did not claim depreciation beginning in the year that the piano was put in service as a business asset? If I don't file amended returns for the past 3 years to claim the depreciation will the IRS still recapture the depreciation I never claimed and will I have to pay tax in the future on the unclaimed depreciation?
