Does the transcript contain sufficient information to carry over deductions, losses, etc., from the prior year?
not everything. but we don't know what items were on your 2019 that would be carryover items for 2020.
you can get a complete copy of 2019 by filing Form 4506 with the IRS. Fee $43. how long this would take is unknown.
