ORIGINAL RETURN WENT FOR UNDER PROCESSING AFTER FILLING REVISED RETURN

If you've filed an original tax return and then a revised one, it's common for the original return to start processing first. The revised return will typically be processed afterwards. If there's a refund involved in both, the original refund may be issued and then adjusted against any difference in the revised return. Be aware that interest might apply if the revised return results in a demand, though it's usually calculated after a notice period.
