When making an Airtable form, you can use prefill_ parameters in the URL of the form to prefill specific fields.

Find the URL for the form you wish to prefill.

Once you get the form URL, you can manually add parameters in the form URL to prefill fields.

Start by adding a ? to the end of the URL.

Then, type prefill_ and the name of the field you wish to prefill. The part after prefill_ must exactly match the actual field name as it appears in the table, not the label used in the form. (Note that spaces in the name of the field will need to be converted to %20s or plus signs (+).)

Once you've typed in the field name, you can then type in an equals sign (=) and the information you wish to prefill. (If there are spaces in the information you wish to prefill, you will need to replace those spaces with %20s or plus signs (+).)

If you wish to prefill more fields, enter an ampersand (&) and then enter more prefill_ parameters.

This URL that you have created will prefill a form for you when access it.
