How can i get a copy of my 2019 1040 to submit for a financial assistance application? I do not want to submit my entire return file to this organization.

See this TurboTax support FAQ for accessing prior year tax return from the IRS:

https://ttlc.intuit.com/community/prior-year-return/help/can-i-get-a-copy-of-my-tax-return-from-the-irs/00/26053

In adobe reader select Print pages "n - n+1" where n is the PDF page with your 1040.

Usually the Form 1040 alone is acceptable.

You'll have to sign it.
