Hello serene,
You can download your daily allowances payment certificate for the last eight years from your ameli account under the section > "Mes démarches en 2 clics" > "Attestation de paiements d'indemnités journalières" > "Une autre période" (you can choose the period you want to make appear on this certificate).
If necessary, you can add the words "Affection de longue durée", "Temps partiel thérapeutique" or "Retenues sociales et impôt sur le revenu".
Remember to save these certificates and keep them for life, as they will enable you to claim your pension rights.
If you do not have yet an ameli account, I suggest you read this topic on How to create my online account "compte ameli" ?.
Finally, if you do not want to open your online account, you can ask your document by calling the CPAM’s English or French Advice Lines.
More information in the following topic: How to call the French Health Insurance Advice Lines?
Have a nice day.
