Hello @Laura Nova
The IRS always checks your return for accuracy, and they reserve the right to re-work the return if they feel it is incorrect. In doing so they will adjust your refund. It seems like this is what happened in your case.
Please visit the IRS using the following link to get your transcript. This transcript will show you their re-working of tour return. The IRS offers two transcripts: online and mail. We recommend you use the online option because it is faster.
