What do you think is messing?
The new 2018 1040 form is only 2 half pages long but can have several other schedules that will only be there if needed.
How do i get all of the pages of my return a lender needs from me for a home loan.
What's missing? There were major form changes this year. Maybe your lender is looking for the old forms which have changed. Ask them what they want.
Under the new tax laws, there are no more simple Form 1040EZ or 1040A's. Everything goes on a little Form 1040 that has six extra "schedules" with it, and if you need any of those schedules, you are not able to use the Free Edition.

Try printing from the Print Center
Log back in your TurboTax account and "add a state" to open the return back up (you are not really adding a state, just to open it back up), then
Click on Tax Tools on the left side of the online program screen.
Then click on Print Center.
Then click on Print, save or preview this year's return. Choose the option Include government and TurboTax worksheets

FYI ... the ONLY thing a lender needs is the return as filed and NOT all the backup worksheets no matter what they say. When printing from the Print Center you have 3 options on how to save the PDF and they only need the first option but you should save the return with & without the worksheets for your records.
