did you have asset additions in 2020? the IRS does not require and Turbotax does not do a 4562 if this is the case. but there should be a depreciation report.
however, if any of the following situations occurred there should have been the form.
• A section 179 expense deduction (which may include a carryover from a previous year).
• Depreciation on any vehicle or other listed property (regardless of when it was placed in service).
• A deduction for any vehicle reported on a form other than Schedule C
