In the Social Security Benefits History panel on your details screen, enter only filing dates for benefits you've actually filed for.
Your Retirement benefit is based on your own work record. Once you have enough credits and are 62, you can file for your Retirement benefit.
Your Spousal benefit is based on your spouse's work record. If you are 62 and meet the other requirements for spousal benefits and your spouse has filed for their own Retirement benefit, you can file for your Spousal benefit.
You could not have filed for your Spousal benefit if your spouse has not filed for their Retirement benefit. So if they have not filed for their Retirement benefit, do not enter a filing date for your Spousal benefit. If you have filed for your Spousal benefit, your spouse has to have filed for their own Retirement benefit so be sure to enter the filing date for your spouse's Retirement benefit on your spouse's details screen. You'll of course also need to enter the filing date for your spouse's Spousal benefit on your spouse's details screen if they've filed for their own Spousal benefit.
Note that the Deeming Provision applies to everyone born on or after 1/2/1954: if you're eligible for both your Retirement benefit and your Spousal benefit and you file for either, you'll be deemed to have also filed for the other and you'll receive the higher of the two. Deeming previously only applied for those filing before their full retirement age (FRA).
