I don't have my AIG number from the last 2 years since I haven't filed

Since you did not file a 2018 return, then for the 2018 AGI put a zero.

Enter a 0 (zero) for the 2018 AGI.

If this is rejected then you will have to print and mail the tax return.

See this TurboTax support FAQ for printing a tax return for mailing - https://ttlc.intuit.com/community/printing/help/how-do-i-print-and-mail-my-return-in-turbotax-online...
