Can I sign electronically if I packed up last year's return and need our numbers?

It sounds like you are looking for your AGI, but you don't have a copy of your return. You can quickly download a free IRS transcript of your return from the IRS website which will include your accurate AGI. Select the blue link above then 'Get transcript online'.

OR, unpack your last year's tax folders.
You will always need last year's tax return and/or records to file the new year.
