Hey @Stella_Shepherd
If you’re using Asana premium, I suggest adding a custom field for time estimation to the Project in question- be sure you select numerical value as the type of custom field. Once you multi-select the Tasks in your Project, Asana will calculate the total sum of the custom fields with numerical values in the Task pane to the right.
A screenshot with additional details from a similar thread are available at the following link below:
With regard to time tracking software, I invite you to take a look at the various time tracking software integrations available to you at the following link:

Hope this help Stella!
