Status changed to Separated as of Apr 2023 and I need to enter spouse income when I am filing my return on Turbotax, however, cannot get info from spouse. May I estimate what the net income?

Hi there, 

My spouse and I separated in April 2023 and I am trying to file my return. However, I am asked to enter my spouse net income and we are no longer in touch with each other, so I know I won't be getting that info from my spouse. I know what my spouse's gross income was in 2022.

Am I able to estimate what the income would be for 2023 and enter that amount in the required field in TurboTax? 

Do I have to enter the income for the entire 2023 or estimate what it would be for the time we were married, i.e. Jan 1, 2023 - April 19, 2023? 

Please advise. 

Thanks.
