An SCorporation has received some, but not all of the ERC claims filed.  It does qualify and so is not withdrawing any of the previously filed claims.  The corp has not yet filed amended SCorp returns for 2020 or 2021 as there are one or two quarters in each year for which the refunds have not yet been rec'd.  Given the time that has passed and it os more than 3 years from the 2020 1120-S original filing date and close to the 2021 1120-S original filing date, should amended SCorp returns be filed now assuming all claims for refund will be rec'd?  Or file amended returns only for the refunds rec'd as of yet and possibly have to file again when the rest are rec'd?
